Correct Answer: 422.5


Solution : J1 = The value of average production of fridges by D and E = $\frac{50+35}{2}=\frac{85}{2}=42.5$
J2 = The total production of television and fridges by all companies
= 60 + 50 + 40 + 30 + 70 + 80 + 30 + 20 + 50 + 35 = 465
$\therefore$ J2 – J1 = 465 – 42.5 = 422.5
Hence, the correct answer is 422.5.
